Abstract
A new methanol maser line at 107 GHz was discovered in five galactic sources. All of them are known Class 2 methanol masers. Toward Class 1 methanol maser sources, the 107-GHz line was found in absorption, or as rather weak quasi-thermal emission sources. The detection of these new methanol masers supports an assumption that the level population inversion is due to overpopulation of some K ladders relative to neighboring ladders.
